4 Claims.

This invention relates to ventilator window frames and more particularly to a ventilator frame for mounting in a window opening of an automobile door, and to the method of making the same.

The invention has for its object to provide a strong, durable and weathertight frame for the pivoted ventilator window that has an elastic and flexible rubber facing permanently aiiixed thereto and that is constructed to have sealing engagement both with the ventilator and with the portions of the wall in which the ventilator is mounted.

With the above and other objects in view, the invention may be said to comprise a ventilator frame such as shown in the accompanying drawings and hereinafter described, together with such variations and modifications thereof as will be apparent to one skilled in the art to which the invention pertains.

Reference should be had to the accompanying drawings forming a part of this specification in which:

.Fig. 2 is a side elevation of the ventilator frame;

Fig. 3 is an elevation of the interior of the forward inclined portion of the frame viewed as indicated by the arrows 3-3 in Fig. 2;

Fig. 4 is a transverse section taken on the line indicated at 4-4 in Fig. 2;

.Fig. 5 is a transverse section taken on the line indicated at 5--5 in Fig. 2;

Fig. 9 is a vertical section taken on the line indicated at 9-9 in Fig. 2;

Fig. 10 is a fragmentary side elevation of the mold which is used to form the rubber facing of the frame and to vulcanize the same to the metal bar which forms the body of the frame; and

Fig. 11 is a vertical section taken on the line indicated at II-II in Fig. 10.

In the accompanying drawings the invention is shown applied to an automobile door which has inner and outer sheet metal panels I and 2 and which has a window opening the margin (Cl. 296-4A) 2 of which is formed by reentrant portions 3 and 4 of the door panels. The reentrant portions 3 and 4 have inturned flanges 5 and 6 which are spaced apart to provide a recess or slot between the panel sections throughout the margin of the window opening. The major portion of the window opening is closed by a vertically sliding glass pane 7, the forward edge of which is guided by a vertical guide post 8. Forwardly of the post 8 the window opening tapers forwardly and has a triangular ventilator window 9 mounted therein. The ventilator window comprises a glass pane having a marginal metalchannel I0 and is mounted to swing on vertically alined pivots II and I2. The ventilator window 9 is mounted in a frame the body of which is formed by a metal channel bar I3 that is bent to conform to the bottom and inclined front edge'of the window opening forwardly of the post 8. The web of the channel bar I3 faces inwardly and the flanges extend outwardly and are received between the inturned flanges 5 and 6 of the door panels. a

The channel bar I3 is provided with a, flexible elastic rubber facing I5 which is permanently bonded to the web of the bar I3. The facing I5 is bonded to the channel bar I3 by molding the facing against the web of the channel bar in a suitable mold and vulcanizing the facing to the bar. As shown in Figs. 10 and 11, the mold may consist of upper and lower sections I6 and H, the lower section being recessed to receive the channel bar I3 and the upper section I6 being recessed to provide a cavity to form the rubber facing I5. f Y

The mold sections I6 and H are elongated and have straight elongated cavities to receive the channel bar I 3 and provide a cavity in which the facing I 5 is molded on and vulcanized to the exterior face of the channel web. After the facing I5 is vulcanized to the bar I3 the rubber faced bar is bent to conform to the window opening. .By vulcanizing the facing to a straight bar the construction of the mold is greatly simplified and a substantial saving is effected in the cost of production.

The composition of the rubber facing I5 may be a rubber composition of a type which strongly adheres to metal when vulcanized thereon, or the metal of the bar I3 may be brass or the like to which rubber is firmly bonded when vulcanized thereon. The rubber facing I5 is wider than the channel bar I3 and has inner and outer edge portions I8 and I9 which project past the inner and outer sides of the bar I3 to cover portions 01' the door panels I and 2 adjacent the slot in which the bar M is mounted. The facing is provided with inner ribs which are adjacent the inner edge of the facing and which project into the window opening to provide stops for the rear portion of the pivoted ventilator 9, the ribs 20 extendingfrom the ends of the bar,;l3.=which abut the post 8 to adjacent the vertically disposed pivots H "and I2.

Forwardly of the pivots H and i2 the facin I5 is provided with outer stop ribs 2! that are offset outwardly with respect to theribs 2E and which limit the outward swinging movement of the forward end portion of .theventilator 9; .The portion of the facing l5 which 'extendsalong the bottom of the window opening is provided with short relatively thin ribs 2,2.spacedoutwardly from the stop ribs 20 over whichthelower edge of the ventilator rides in moving to closedposition. The portion of the facing along the bot itomiof the window-openingforwardlyv of 4.7118 pivot 12 1-has a shorterelatively thin rib 23 spaced inwardlyr'from the :stop rib 24 over which. :the forwardportionof the bottom edge ,of the ventilator :rides when the ventilator is moved to elosedpo- T "is closed the :lflexible portions .25. and "-27- .of the .Iibs areiflexed towardatheribs .ZDQand .2-l and col.- lapsed against the-pivot l to provide -a tightseal :atxthe pivot. The short-ribs 2 .and 7,23 on oppo- :sitesides :of the lower .pivot J2 form extensions of the .ribs Ze-andd! and are collapsed-around the :pivot sby-the ventilator in pissing in a Ill anvnersimilar to the flexible ribs 26 and 21.

The frame of Y the ,present invention is .posi- :tionedin .a window :opening by. the rubber Lfacing l5 whichhas sealing engagement both with the ,pivotedwentilator ,9 and also with the inner and -outer doorpanels .to effectively seal the window when the ventilatoris closed. The vertical ,guide post 8 provides .-a seat for the rear vertical edge of the ventilator .and may 'be' provided with the usual :sealing strip. ,Byreason or the bonding of the :mbber facing. in the-rigid metal jirame, the sealing :ribs are accurately positioned and. firmly 'held'in proper position with respect*to"the pivote.d ventilat,or.- Also by reason of thefirrnLbond betweenrtherubberfacingand the iframexbar, it is unnecessary to provide any fastening means other -.than the rubber facing strip between "the ventilator frame and the door panels.
